Michael Burns/Burnes Georgia to Florida

I'm looking for any info on my g.g.grandfather Michael Burns who I believe may have been born "Burnes" in Georgia between 1814 and 1825. Census records show he was born in GA (in the timeframe above) He lived most of his adult life in The Tallahassee area (Spring Hill, Leon Co FL) and was married to Elizabeth Geddie. There is a Civil War Pension app that has her name misspelled as Geddir. Other than his children's names, I know little about him. I'm hoping someone can find him in their tree in GA and lend some insight into his origins.
